Application lled Kay 12, 1926. Serial No. 108,607.

. vide the conveyer with a nose or plow which is arranged at one sidethereof so that the conveyer can be forced under a pileof materialwithout damage to the conveyer part.

A further object of the invention is to provide power driven means formoving the conveyer, or a portion thereof, transversely under a pile ofmaterial or tea position where the material will fall when knocked down.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing my invention in detail, reference will i be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which 1 Figure1 is a plan view showing the device in use in a mine.

Figure 2 is an elevation of Figure 1.

Figure 3 is a section on line 33 of Figure 2.

Figure 4 is section on line 4.4 of Figure 3. v

In these views, A indicates a sectional conveyer which is composed ofthe horizontal I-beam 1 and the endless member 2 which platform and beambeing formed with each section. The platform extends beyond the inner.edge of the conveyer and a plate 9 is connected with the extended edgeof said platformand slopes upwardly at an angle andissupported by thetop edge of the inner flan e. of the beam 1. This plate and the exten edpart of, the platform forms a shoe or plow which enables the device tobe moved transversely under a pile of material, the plate 9 protectingthe edge of the conveyer from the material.

A plurality of stub axles 10 have their bases ll bolted to the beam 8and drums 12 are rotatably supported by said axles. A cap 13 is boltedto each drum and'a screw shaft 14 is pivoted to each cap. A nut member15 engages each shaft and said member is pivoted in a block 16 to whichthe forked lower end of an upright17 is pivoted. Each upright isprovided with a threaded socket "to receive a threaded shaft 18 whichhas its outer end pointed and a point 16' is formed on'the base of eachblock 16. Thus the blocks 16 can be clamped to the mine floor by turningthe shaft 18 in the upright 17 to cause its pointedend to engage theroof of the mine, while the block engages the floor. i

A pair of cables 18 engage the drums 12 and are connected with the drumsor winches 19 which are geared to the shaft of motor 20, so that thedrums can be rotated in either direction from the motor. As will beseen, when the drums are turned, the shafts turn in the nut members 15and thussaid shafts will be moved longitudinally and they will carrywith them the drums, the conveyer support and the conveyer. Thus theconveyer can be forced under a pile of material or it can be movedtransversely against the mine face so that the material knocked from theface will fall upon the conveyer. Then by starting up the motor 6, thematerial will be fed by the conveyer from the pile on to a secondconveyer B which will convey it to a point of discharge.

The various sections may be connected together as. shown at 21 and eachcap 13 maybe provided with a hole 22 for receiving a cross-bar or thelike so that the parts can be turned without using the motor.

The beam 8 should be sufliciently high to'prevent the material droppingover the same upon the drums and the plate 9 most extend over theconveyer a sufiiclent" distance to protect the parts thereof from thematerial when the device is beingforced under a pile of material.

tion that the advantages and novel features of my invention will bereadily apparent.

I desire it to'be understood that I may make changes in the constructionand in the combination and arrangement of the several parts, providedthat such changes fall Within the scope of the appended claim.

What I claim is 9 An apparatus of the class described,

comprising a platform having'a vertical part at one edge, a shoe or plowat the other edge, a conveyor on the platform between the vertical partand the plow, stub axles con- 'nected with the vertical part, a drum oneach axle, a cap connected with each drum, a screw shaft connected witheach cap, a nut member on each shaft, a block in which the nut member ispivoted, an upright having a forked lower end pivoted to the block andhaving a threaded socket in its upper end, a threaded shaft engaging thesocket and having a pointed end engaging the roof of a mine, cablesengaging the drums, Winches on the platform and to which the cables arefastened and a motor for driving the Winches;

In testimony whereof I, aifix my signature.

JOHN W. POWELL.
